The best proposal We have now for what is occurring is formation of the cyclic halonium ion, and that is a three-membered ring bearing a favourable official demand to the halogen.In case you attract this mechanism in an Test, publish the terms "induced dipole" close to the bromine molecule - to show that you understand what's going on.The listing o

What was discovered alternatively is this response is also hugely stereospecific, much like the response of cisThe predominance of allylic substitution about other positions is based on bond dissociation energies. An allylic C-H bond has a toughness of about 88 kcal/mol which can be much weaker than a normal alkyl C-H bond (ninety eight kcal/mol) o
